Reaction of variety Lileya to planting density (40000 and 50OOO plants/ha) and seed tuber size (20-30 mm, 35-55 and 60-80 mm) was evaluated while developing basic elements of table potato technology for tuber weight of 300 g and more. Increased row-spacing from 70 up to 90 cm did not influenced the yield, but positively influenced on number of large tubers and made 31,8-45,2%. At growing Lileya variety by tuber size 60-80 mm, with row-spacing 90 cm, lanting density 50000 plants/ha and usage of cultivator KGO-3,6 maximal yield of large tubers made 21,3 t/ha. At developing the basic elements of technology of large tubers growing it is established the following: agricultural machines applying of AK-2,8, OKG-4, KGO-3,6 and PAN-3,6 models provide agrophysical soil indicators (density, humidity, lump state) necessary for large tubers forming. Usage of PAN-3,6 model allows to get more porous soil at the first period of potatoes vegetation in comparison with cultivators AK-2,8, OKG-4, KGO-3,6 (passive-active working parts)
